NVIDIA looking for a piece of next-generation smartphones shouldn't come as much of a surprise to anyone, but CEO Jen-Hsun Huang dropped a few details in a recent email to staffers that's sure to spur at least a little excitement. As AnandTech reports, in addition to marking the launch of the company's new Kepler-based GeForce GTX 680 graphics card, he also looked towards future possibilities for the GPU, noting that "today is just the beginning of Kepler," and that "because of its super energy-efficient architecture, we will extend GPUs into datacenters, to super thin notebooks, to superphones." Not surprisingly, that's about as specific as things got as far as mobile devices are concerned, with no mention whatsoever as to when we might see such Kepler-based "superphones."
